Bhagwad Gita
Chapter 14, Verse 24
समदुःखसुखः स्वस्थः समलोष्टाश्मकाञ्चनः।तुल्यप्रियाप्रियो धीरस्तुल्यनिन्दात्मसंस्तुतिः।।14.24।।
Who is the same in pleasure and pain, who dwells in the Self, to whom a clod of earth, a stone, and gold are all alike, who is the same to the dear and the unfriendly, who is firm, and to whom censure and praise are one and the same.
